Door procedure, when not rushed. It does not include the Trap Spotter free checks.

At each door, check for sounds or traps. Take 10 then roll twice.
[dice=Perception]10+22+4[/dice]
[dice=Perception]d20+22+4[/dice]
[dice=Perception]d20+22+4[/dice]

If trapped, try to disarm it. Take 10 then if needed roll up to twice.
[dice=Disable Device]10+24[/dice]
[dice=Disable Device]d20+24[/dice]
[dice=Disable Device]d20+24[/dice]
At this point if nothing blew up, I would like a chance to evaluate things.

If it is locked and there is only one obvious way forward, try to unlock it.
[dice=Disable Device]10+24[/dice]
[dice=Disable Device]d20+24[/dice]
[dice=Disable Device]d20+24[/dice]
At this point I would take 20 to unlock.
